Back in the early posts there were some really
interesting things being discussed with major contributions by Donald Eastland
and others about the effects of pH, micronutrients, temperature patterns
and so on as to how they affected SA _expression_. I was impressed with the
richness of information available. --That's the reason I'm willing to take
the time and make the effort to dress up or clean up those files so that they
can be accessed. There's a gold mine of information in them.
Just for the fun of it I've submitted an article
for the Spring Tall Talk that is a bit of a spoof with a rather serious
purpose. Entitled, "Why doesn't my FAT FLOUNCY look like
yours?" The piece addresses variability in bearded irises--which are
more conspicuous with the SA's than any others.
The point being made is that all bearded irises
vary greatly. Their complex hybrid origins with some extraordinarily
different climates involved in the ancestries leave the modern plants never
sure where or when or how to grow and bloom. Differences in pH, soil
micronutrients, sun exposure, cultural practices of the grower--and God alone
knows what else make whopping differences. The ancestral species were
adapted optimally to a wide variety of soils, climates, rainfall and temperature
cycles. We've stirred all that together in one pot. It is amazing
that so many varieties do perform as well as they do in a wide range of
climates. Their ancestors weren't so flexible.
I just wish I had read those early posts before I
wrote the piece--they often said what I wanted to say--better than I
could.
Variability is really pronounced as an issue when
judging a show. I have never ceased to be amazed at how different the same
variety can be coming in from several gardens. It isn't just SA's--it's
all of them.
There was discussion back then about the intensity
of anthocyanin pigments varying with temperature at time of blossom
formation. That was new to me--and explains a lot of things I've
noticed. Here in the Asheville area we have had a lot of variation in
temperature profiles over the past several years. Some varieties have
shown marked year-to-year variations I didn't understand. Now, at least, I
have a clue.
